Help Needed to ID this manual shifter

Late to the game as well, but judging by the terrible wrinkling in the tunnel stamping, it's an F/M-body floor extension. The paint color is a dead ringer for '80/'81 M9 Baron Red, too. The shifter is an Inland item, likely the "lift to reverse" unit. The later Inland/ITM look much more "Hurst-y" (the Hurst will even bolt to the ITM bracket) but they're totally different internally. The rods do not interchange with Hurst units despite looking very similar. The ITM bracket has a different offset so the bends are wrong.

Here's my own F/M-body floor tunnel (which also fits J-bodies, for the record):
